Check your owner's manual carefully for recommendations about winter driving. SUVs call for different handling skills than other vehicles.
Slow down and increase the distance between other cars while driving on snow or ice-covered surfaces. Although your higher ground clearance helps you get going quicker in heavy snow, it won't help you stop quicker.
Apply firm and constant pressure on the brake pedal if you have antilock brakes. Pump the brakes to prevent wheel lock up if you don't have antilock brakes.
